E65 Sub-Bus Systems: Notes

In addition to the bus systems, sub-bus systems are also used. These are subordinate serial bus systems. Their functions correspond to those of the previous I/K bus. The following sub-bus systems are fitted on the E65:

• Driver's door P bus (driver's door switch block periphery bus)
• Engine LoCAN (engine Low CAN bus; link between DME and Valvetronic control unit)
• Telcommander CAN (Phone board CAN)
• M bus (air-conditioning motor bus)
• DWA K bus (alarm system body bus)
• BSD interface (bit-serial data interface)
